Valued for its branched aliphatic side chain, Fmoc-L-Ile-OH (CAS No. 71989-23-6) plays a key role in the synthesis of hydrophobic segments in peptides. It’s widely used in Fmoc-SPPS for GLP-1 analogs such as Semaglutide and Tirzepatide. This protected isoleucine ensures reliable coupling efficiency and high structural fidelity throughout peptide chain assembly.
